Physical Review X, 2017 We study the statistics of infima, stopping times, and passage probabilities of entropy production in nonequilibrium steady states, and we show that they are universal. We consider two examples of stopping times: first-passage times of entropy production

Entropy Production of Run-and-Tumble Particles [PDF]
EntropyWe analyze the entropy production in run-and-tumble models. After presenting the general formalism in the framework of the Fokker–Planck equations in one space dimension, we derive some known exact results in simple physical situations (free run-and ...

Calculation of the Entropy Balance Equation in a Non-equilibrium Reaction-diffusion System
Entropy, 2010 In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model.

Cavitation Characteristics and Structure Optimization of Two-Dimensional Valve Based on Entropy Production Theory [PDF]
Journal of Applied Fluid Mechanics, 2023 In addition to noise and vibration, cavitation also lowers the efficiency, performance, and working lives of two-dimensional valves. To study the effect of cavitation on the flow characteristics of two-dimensional valves, standard turbulence model and ...

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory
Energies, 2022 A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...

The entropy production for thermal operations [PDF]
Scientific Reports, 2020 AbstractAccording to the first and second laws of thermodynamics and the definitions of work and heat, microscopic expressions for the non-equilibrium entropy production have been achieved. Recently, a redefinition of heat has been presented in [Nature Communications volume 8, Article number: 2180 (2017)].

Entropy Production in Quantum is Different [PDF]
Entropy, 2019 Currently, ‘time’ does not play any essential role in quantum information theory. In this sense, quantum information theory is underdeveloped similarly to how quantum physics was underdeveloped before Erwin Schrödinger introduced his famous equation for the evolution of a quantum wave function.
